-Application filed June 24, 1908. Serial No. 440,203.

To all whom it may concern:

Be it known that I, VERGIL MULHOLLAND,

. a resident of Edgewood, in. the county t Allegheny and State of Pennsylvania, have invented a new and useful Improvement 1r Apparatus for Handling Glassware; and

do hereby declare the following to be a full. clear, and exactdescriptiou thereof.

' -My invention relates to apparatus for handling glassware, the object of the invention being to provide for the handling of the a line 4-4, Fig. 2; Fig. 5 is a side elevation of the inner end of the conveyer showing the apparatus for transferring the ware from the conveyor to the leer; Fig. 6 is an en-' larged view of the transfer device; Fig. 7 is an enlarged detail; Fig. 8 is a detail of intermittent drive; Fig. 9 is a side view of the fire polisher; Fig. 10 is an enlarged view of the mechanism for the intermittent feed for the leer conveyer; Fig. 11 is an end view of the chute; and Fig. 12 is an end viewv partly in section.

I have illustrated myinvention as used inconnection with a molding apparatus in which the ware is discharged by gravity from the mold, the mold opening automatically as the revolving table carrying the same comes around into proper position. I have not deemed it necessary, however, to

illustrate such molding apparatus in detail but-have simply illustrated the same n d agrammatic form, as my invention pertains in no way to such molding apparatus. Accordingly the numeral 2 des1gnates the ro-, tary table of such molding apparatus and hinged to said table is the arm 3 which carries the artible mold 4, said mold in this instance lieing for a form suitable for mold ing a bottle 5. "The arm 3 has the roller 6 "whichds'adapted to travel on the track 7,

.said track being arranged in such a way as to provide for the tilting of the mold in the manner indicated in Fig. 4, while at the same time the mold is opened automatically to allow the bottle to be discharged therefrom. At the point where the moldfl opens to discharge the bottle is located the chute 8 which has the flaring mouth portion 9 cut away, as at 10. Extending across the mouth of the mouth portion 9 at the upper end thereof is the deflector rod 11 which may be provided with the covering 11" of asbestos, or other suitable material. The mouth piece .9 is arranged at the proper angle to receivc the bottle as it is discharged from the niold and said mouthlpiece fits into the curved chute 8. The chute 8 is cut away,

as at 8", to permit of the travel of the bottle as fully hereinafter set forth. A contact arm 12 is pivoted at 12 to'the chute 8, said arm entering said chute through a slot-13 and counterbalanced or weighted by the end portion 14 so that said contact arm is normally in position within the chute to be in the path of the descending bottle and forced outwardly thereby. A contact finger 15 is pivoted at 16 to the chute and the contact 21111111 is adapted to be forced outwardly by the descending bottle so as to contact with the contact finger 15 and so form the electrical circuit hereafter referred to.

Arranged in proper position with reference to the chute 8 is the frame 17 which forms the support and guide-way for the endless chain 18 which carries at intervals -the cups 19. The chain 18 passes around with air and gas by means of the pipe 25.

These burners 24 are upon the order of a Bunsen burner and the flame is discharged downwardly so as to ,strike the upper end of the bottles carried by the cups 19, said burners being arranged in position to act upon the said bottles when they stop intheir intermittent movement, RS'PIOVldQd for, so

that the bottles are fire-polished asthey are carried intermittently to the opposite;

" whole, is derived from the motor 27. The

pinion 28 on the motor shaft 28 meshes with the gear wheel 29 on the shaft 30. The pin- 3 ion 31 on the shaft 30 meshes with the gear wheel 32 on the shaft 33. The shaft 33 carries the clutch 34. Ash-aft 35 in line with the shaft 33 has the slidable clutch 36, said clutch having the cam 37. A spring 38 is interposed between the clutch 36 and the collar 39 on the shaft 35, said spring acting to normally hold the clutch 36 in engagement with the clutch 34. A solenoid 40 has the roller 41 which is adapted to engage the cam 37 for the purpose of withdrawing the clutch 36 in the manner fully hereinafter set forth. "Wires 43 and 44 are connected with the solenoid and to the contact arm 11 "and contact finger 15 so that'when the said extending from said hubs are the arms 48 arm and finger are brought into contact by the descending bottle the solenoid-40 will be withdrawn, permitting the spring 38 to act to throw the clutch 36 into engagement. with the clutch 34.

To give the intermittent movement to the chain 18 the shaft carries at its outer end the disk44, said disk being cut away, as The disk 44 has the hubs 47 and within which the roller 49 is mounted. A shaft 50 carries the wheel 51 which is provided with the deep teeth or pockets '52 at intervals. The periphery of the wheel 51 is provided with the depressions 53. Secured to the shaft 50 is the beveled gear 54 which meshes with the bevel gear 55 on the quently to the chain 18. Upon each move-- vertical shaft 56 which carries the sprocket wheel 21. As the shaft 35 rotates the disk 44 will rotate and the roller 49 carried by said disk will enter the pockets 52 and the wheel 53 will be rotated, the said roller 49 descending within'the pockets 52 withdrawing therefrom during the rotation of the wheel 53 whereby an intermittent movement is imparted to said wheel 53' and consement of the chain 18 one of the cups 19 "is moved around in position at. a' standstill directly'beneath the chute'1f8 to receivea bottle therefrom, while at thesame time a cup carrying a bottle also comes around'in po- 63 for the shaft 64. A casting 65 encircles the shaft 64 and is adapted to move up and down thereon. This casting 65 has the links 66 depending therefrom and said links are connect-ed to the jaws 67. These-jaws 67 are hinged as at- 68 to the stationary collar 69 on the lower end of the shaft 64. A lever 70 is fulcrumed at 71 on the bracket 72 of the frame 62 and said lever is pivotally connected to the casting 65 at 73. v The inner end of the lever 70 is bifurcated, as at 74, and in the ends of said lever are the slots 75 with which the pins 76 on the collar 77 engage. This collar 77 is slidable on the sleeve 61. Below the collar 77 is the collar 78 which is slidable on the sleeve 61 and said collar is link is connected to the rod 83 sliding in guides 84. At the outer end of the rod 83 V is the idle roller 85 which is adapted to rod carries the idle roller 94 which is adaptr ed-to engage with the cam 95 on the shaft 35. Secured to the lower end of the shaft 60 is the crank 96. An arm 97 is connected to the crank pin 98 and at its opposite end said arm is connected to the rod 99 adapted to slide in the bearings 100. A spring 101 is interposed between a collar 102 on said rod and the bearing 100. At the outer end" of the. rod 99 is the idle roller 103 which is sha 35. The transfer mechanism just describedis-adapted to be used in connection with a device for conveying the-ware into the leer 105. A conveyer 106 is arranged with reference to the leer so as to arrange the ware in rows upon the pans 107 of the her and this conveyer comprises an endless chain passing around the sprocket wheels 108, 109 and 110.- Flights 111 are secured to the conveyer 106 and the ware conveyer and passed into the leer by the opening 112 at the side of the leer near adapted to engage the cam 104 on the j is to be arranged between the flights of the f the end. All intermittent movement must be imparted to this conveyer 106v and this intermittent movement is provided for in the following manner: On the shaft 33 is the beveled pinion 113 which meshes with the beveled gear 114. On this beveled gear 114 is the crank 115. A rod 116 connects the crank 115 with the crank 117 on the vertical shaft 118 on which the sprocket wheel 10.8 is secured. On the bottom face of the sprocket wheel 108 are the ratchet teeth 119. A pawl 120 pivoted on the bracket 121 is adapted to engage the ratchet face of the sprocket wheel 108 and so impart an intermittent movement to said sprocket Wheel and consequently'to the conveyer 106.

When my improved apparatus is in use the bottle contained in the mold 4 will be discharged by the tilting and openin of said mold so as to fall in the position indicated in Fig. 4 into the mouth of the chute. In order to insure the bottle descending the chute with its bottom down the rod 10 is provided with which the neck of the bottle in dropping comes in contact so that the heavier portion of the bottle being below the neck the weighted end will .carry the bottle down so that it will pass from the chute in the position indicated in Fig. 4. As the bottle descends the chute it comes in contact with the arm 11 and forces said arm out= wardly, bringing said arm into contact with the contact finger 15. This forms the circuit to the solenoid 40 and for the purpose hereinafter stated. The bottle drops into the cup 19 in position to receive it and as soon as said bottle is deposited within-the cup'19 movement is imparted to the conveyer 18 which moves the cup around into position where the bottle is acted on by the fire polisher or burner 24, while another empty on is brought. around in position beneath t e chute 8 to receive the next bottle. This intermittent movement is pro-- the chute 8 the solenoid 40 is withdrawn,

allowing the spring 38 to throw the clutch 36 into engagement with the clutch 34. During the time that the bottle was in contact with the contact arm 11 the solenoid 40 was in contact with the cam 37 of the clutch 36 and as said cam rotates the clutch 37 is withdrawn from the clutch 34, stopping the travel of the conveyer 18 until the bottle has dropped into the cup 19, whereupon the electrical circuit to the solenoid is broken and the solenoid withdrawn, permitting thespring 38 to force the clutch 36 into engagement with the clutch 34. Further movement is then imparted to the conveyer 18 and the next empty cup is moved around in fire polished, whereupon it continues around until it reaches the point where it is to be picked up from the cup and carried over and deposited between the lights of the conveyer 106. The apparatus is so timed that the frame 62 will be in position over the cup so as to lift the ware therefrom. Accordingly the cam 86 is in such position with reference to the idle roller 85 that the rod 83 will be forced back in such position as to cause the bell crank 81- to raise the rod 80 and with it the collar 78. The collar 78 lifts the lever and the jaws 67 are opened. With the frame 62 in this position the cam 86 having revolved moves the rod 83 so as to permit the rod to lower and the collars 76 and 78 are lowered. This movement of the collar '76 through the lever 70 acts to cause the jaws 67 to grasp the upper end of the bottle contained within the cup. The cam 95 meanwhile has moved around in posit-ion to so act upon the rod 93 to'operate the bell crank 91 to lift the rod and with it the sleeve 61'. The sleeve 61 moves up the shaft 60 and carries with it the frame 62. This upward movement of the sleeve 61 continues until the bottle has been lifted clear of the cup, whereupon the cam 104 has moved around in such position with reference to the'idler 103 on the rod 99 as to move said rod to impart a rotary movement through the crank 96 to the shaft 60. This rotary movement imparted to the shaft 60 carries the frame 62 around into'the position indicated in full lines,Fig. 3, bringing the bottle over into position above the conveyer 106v between the flights of said conveyer. At this point the frame '62 is to be lowered and accordingly the cam has traveled around in such position as to effect the lowering of the sleeve 61, whereupon the bottle is lowered onto the conveyer 106.-

, and the jaws 67 are thrown apart, releasing the battle. In this manner the bottle is deposited between the flights of the conveyer 106 and this conveyer 106 now moves one step to provide for the deposit of the next bottle upon the conveyer. This intermittent movement of the conveyer 106 is provided for by the intermittent movement imparted to the sprocket wheel 108 through the pawl and ratchet mechanism hereinbefore described. It is now necessary to swing the frame 62 around in position to bring the jaws into position to' receive and grasp another bottle. Accordingly the cam I04 has rotated in such position with reference to the idler 103 as to impart the rotary movement to the shaft 60 to swing the frame 62 around in position to be lowered to grasp I transfer of theware from the moldto the leer carrier. The whole device worksautomatically, the act-ionof the bottle in drop ping by gravity from the mold into the cup acting to control the movement of the conveyer and all the parts being so timed as to cooperate with each other in such a way as to produce the result described. The bottle as received from the mold is deposited in an upright position in the cups and it is not necessary to carry it around in an inverted form but it isin an upright position from the start and continues in this position until deposited in the leer.
